WILLIAM W. MORGAN, OF HOLLYWOOD, CALIFORNIA.

SURVEYORS REEL.

Specification of Letters Patent.

Patented Nov. 1, 1910.

Application led February 7, 1910. Serial No. 542,577.

To all whom it may concern:

Be it known that I, VILLIAM W. MORGAN, a citizen of the United States,residing at Hollywood, in the county of Los Angeles and State ofCalifornia, have invented a new and useful Surveyors Reel, of which thefollowing is a specification.

This invention relates to improved measuring tape for use by surveyorsand the main object of the invention is to provide means whereby thetape may be held or locked in definite position after it has been runout to measure a definite length.

It is often necessary or desirable in surveyino to use the same lengthof tape repeate ly, the tape being used in the manner of a chain, and itis also desirable after the tape has been ru-n out for measurement toretain the measurement until an opportunity is afforded for recordthereof. The present invention provides means whereby such retention ofthe tape can be quickly and readily effected.

The accompanying drawings illustrate the invention and referringthereto: Figure 1 is a perspective of the tape measure in lockedposition. Fig. 2 is a similar view showing the device in unlockedposition. Fig. 3 is a fragmentary sectional view of the device takenlongitudinally of the tape support. Fig. 4f is a transverse section onthe line www4 in Fig. 3. Fig. 5 is a perspective of the tubular arbor'for the tape reel.

The invention is illustrated as applied in connection with the usualform of surveyors tape, the tape indicated at 1, carried by a reel 2journaled in a frame 3, said reel 2 being provided with a handle 4 forwinding the reel and the carrier frame 3 being provided with a handle 5in the usual manner.

The reel 2 is mounted on the frame 3 by means of a tubular arbor 6ourna-led in top and bottom plates 7, 8 of the frame 3. The top plate 7is preferably reinforced by an additional plate 9 serving as a guideplate for the locking means hereinafter described and the tubular arbor6 extends upwardly through this top plate 9 and is provided with tw'odiametrically opposite notches or slots 10 registering with alongitudinal slot or way 11 carried in the top plate 9. The

slots l0 and 11 are preferably undercut or dovetailed as shown. A slidinbolt or locking member 12 is mounted in t e slot or way 11 to slidelongitudinally therein, the edges of said bolt 12 being fiareddownwardly to fit the undercut slots 10 and 11, thereby retaining thesaid bolt in place. The to plate 9 is secured in place on the plate 7 ater the bolt 12 is put in place and said top plate 9 serves to hold thebolt in position. Bolt l2 is further provided with an upwardly extendinglug or projection 13, whereby the bolt may be manually operated to moveit into or out of locking position. A spring indicated at 15 ispreferably provided at the bottom of the way 11 beneath the sliding bolt12 and engaging the bottom of said sliding bolt to hold the samefrictionally in position.

l/Vhen a measurement is being made or the tape is being run out, thebolt 12 will be withdrawn to position shown in Fig. 2, leaving the reelfree to turn. has been unwound to the required extent and it is desiredto retain or set it at that length, the bolt is shoved forwardly toposition shown in Fig. 1, causing the bolt 12 to engage in the notches10 1n the arbor of the reel. It will be understood that in order toeffect such locking of the reel, the reel must be turned to position tobring the slots 10 into register with the slot or way 11 and the bolt12, but as this requires not more than one-half of a revolution of thereel in one or the other direction, it can be readily effected withoutmaterially disturbing the reading point on the tape.

What I claim is 1. A surveyors tape comprising a reel provided with atape and with an arbor, the arbor having an undercut slot extendingdiametrically across its end, a frame in which said arbor is journaled,and said frame having a way, a bolt slidably mounted in said way andadapted to engage the slotted portion of the arbor, said bolt having aprojection serving as a manually operating means.

2. A surveyors tape comprising a reel provided with a tape and with anarbor, a frame in which said arbor is journaled, said arbor having adiametrical slot across its When the tape end, and said frame having aWay extending my hand at Los Angeles, California, this .1stdiametrically of said arbor, a bolt Slidably clay of February 1910. 1nountedin said Way and adapted to envao'e the slotted portion of thearbor, and Sp'iig ILLIAll/L W' MORGAN' means engaging said bolt forholdingY said In prsence of-H G. T. HACKLEY,

bolt in locking or unlocking position.

In testimony whereof, I have hereunto Set FRANK L. A. GRAHAM.
